I'm running a scale regression setup on :
=========================================
OpenShift 4.13.2
OpenShift Virtualization 4.13.1
OpenShift Container Storage - 4.12.4-rhodf

this is a large-scale setup with 132 nodes running 6000 RHEL VMs on an external RHCS.
after powering up 3000 out of 6000 VMs I opened the UI and see thousands of the following warnings regarding virt-handlers memory consumption:

============================================================================================================================================

25 Jun 2023, 11:58
Pod virt-handler-hmztx cpu usage exceeds the CPU requested

from oc adm top:

============================================================================================================================================

virt-handler-x46kr 12m 314Mi
virt-handler-pld9d 21m 315Mi
virt-handler-sfqnh 17m 316Mi
virt-handler-dlh4w 26m 317Mi
virt-handler-lbfj7 17m 317Mi
virt-handler-tcx9l 24m 319Mi
virt-handler-fggsg 18m 321Mi
virt-handler-7gzm8 17m 325Mi
virt-handler-lk9bp 12m 325Mi
virt-handler-gcwfh 18m 329Mi
============================================================================================================================================

if you look at the screenshot I attached you will see that because of it the status of OpenShift Virtualization is at a "Degraded" state
in addition, the thousands of warnings cause the console to significantly slow down and freeze.

I collected the logs but I found it odd that I could not see the above events via cli, note this is a 44G folder when extracted:
